2.0L Turbo Diesel (OM654M) - CLE 220d
Diesel
Test drive task: Perform a cold start check. | Advice: Listen for any irregular rattling or injector noise during the first few seconds of idling; in newer common-rail diesels, smooth operation is key.
Test drive task: Evaluate the 9G-TRONIC transmission. | Advice: During gear changes at lower speeds, pay attention to the shift quality. It should be seamless; any hesitation or 'hunting' for gears might suggest a need for software recalibration.
Test drive task: Inspect the MBUX display and infotainment interface. | Advice: Spend a few minutes navigating the menus while stationary to ensure the touch responses are fluid and that there are no flickering pixels or connectivity lag.
Test drive task: Examine the frameless door seals. | Advice: While stationary, inspect the rubber seals around the windows and doors. Being a pillarless coupe design, ensuring these are in good condition helps prevent wind noise and interior moisture.
Scheduled minor service including oil and filter changes.
Consider transmission fluid service and replacement of fuel filters for optimal OM654M performance.
Comprehensive inspection of auxiliary drive belts and DPF health monitoring.
Always use Mercedes-Benz approved low-ash engine oil to protect the sophisticated emissions systems.
Keep a close eye on your AdBlue levels, as the OM654M engine relies on this for cleaner emissions.
Regularly clean the sunroof drainage channels to prevent water ingress in the cabin.
Ensure tyre pressures are checked frequently, as low-profile tyres on these models can be sensitive to potholes.
Book your service through an experienced specialist to ensure the digital service history is accurately updated.
Estimated repair costs if issues arise
If you primarily drive short distances, the DPF may eventually require a professional regeneration or deep clean. It is good practice to occasionally take the car for a longer drive on the open road to keep the system happy.
Depending on the specific configuration of your CLE, complex suspension parts can eventually show wear. If this component needs attention in the future, it involves replacing electronic actuators or bags.
As the car ages, the secondary battery supporting the mild-hybrid system may reach the end of its cycle. You might eventually need to budget for a specialized replacement to maintain the start-stop functionality.
